通过双能 X 射线吸收测定法 (DEXA)、磁共振成像 (MRI) 和水密度测定法，对 13 名未经训练的健康男性 [60 +/- 4 (SD) 年] 评估了为期 16 周的力量训练计划对总体和局部身体成分的影响。另外九名男性（62 +/- 6 岁）作为非活动对照。力量训练计划显着提高了上半身力量（39 +/- 8%；P < 0.001）和下半身力量（42 +/- 14%；P < 0.001）。通过 DEXA 测量，总去脂质量 (FFM) 增加了 2 kg（62.0 +/- 7.1 至 64.0 +/- 7.2 kg；P < 0.001），总脂肪质量减少了相同的量（23.8 +/- 6.7 至 21.8 +/- 6.0 kg；P < 0.001）。当通过水密度测定法测量时，观察到 FFM 类似的增加（61.3 +/- 7.8 至 63.0 +/- 7.6 kg；P < 0.01）和脂肪量的减少（23.8 +/- 7.9 至 22.1 +/- 7.7 kg；P < 0.001）。通过 DEXA 测量时，手臂（6.045 +/- 0.860 至 6.418 +/- 0.803 kg；P < 0.01）、腿部（19.416 +/- 2.228 至 20.131 +/- 2.303 kg；P < 0.001）和躯干（29.229 +/- 4.108 至30.134 +/- 4.184 kg；P < 0.01），而手臂（2.383 +/- 0.830 至 2.128 +/- 0.714 kg；P < 0.01）、腿部（7.583 +/- 1.675 至 6.945 +/- 1.551 kg；P < 0.001）和躯干的脂肪量减少训练结果（12.216 +/- 4.143 至 11.281 +/- 3.653 kg；P < 0.01）。（摘要截断为 250 字）
The effects of a 16-wk strength-training program on total and regional body composition were assessed by dual-energy X-ray absorptiometry (DEXA), magnetic resonance imaging (MRI), and hydrodensitometry in 13 untrained healthy men [60 +/- 4 (SD) yr]. Nine additional men (62 +/- 6 yr) served as inactive controls. The strength-training program resulted in substantial increases in both upper (39 +/- 8%; P < 0.001) and lower (42 +/- 14%; P < 0.001) body strength. Total fat-free mass (FFM) increased by 2 kg (62.0 +/- 7.1 to 64.0 +/- 7.2 kg; P < 0.001), and total fat mass decreased by the same amount (23.8 +/- 6.7 to 21.8 +/- 6.0 kg; P < 0.001) when measured by DEXA. When measured by hydrodensitometry, similar increases in FFM (61.3 +/- 7.8 to 63.0 +/- 7.6 kg; P < 0.01) and decreases in fat mass (23.8 +/- 7.9 to 22.1 +/- 7.7 kg; P < 0.001) were observed. When measured by DEXA, FFM was increased in the arms (6.045 +/- 0.860 to 6.418 +/- 0.803 kg; P < 0.01), legs (19.416 +/- 2.228 to 20.131 +/- 2.303 kg; P < 0.001), and trunk (29.229 +/- 4.108 to 30.134 +/- 4.184 kg; P < 0.01), whereas fat mass was reduced in the arms (2.383 +/- 0.830 to 2.128 +/- 0.714 kg; P < 0.01), legs (7.583 +/- 1.675 to 6.945 +/- 1.551 kg; P < 0.001), and trunk (12.216 +/- 4.143 to 11.281 +/- 3.653 kg; P < 0.01) as a result of training.(ABSTRACT TRUNCATED AT 250 WORDS)
